PTS845 series, the small and compact size side actuated tactile switch, has a size of only 4.5 x 3.4 x 3.3 mm. With the small and compact size, the switch allows designers to either free up space in PCB to add additional functionality, or reduce the overall size of their design. 80, 160 and 260 gf operating forces, which are the most common versions used in the market, are available. Bracket peg design of the switch provides premium quality and performance. PTS845 tactile switch accommodates a wide range of applications in the high-end consumer wearable and medical device markets, where compact solution is required.
